Heat Transfer of Natural Convection Flow Between Inclined Plate with Heated Face Upward and Air

The study for the natural convective heat transfer from an inclined plate with the different angles submerged in air, with heated surface upward, is performed experimentally. The plate was heated with electric heating, the average surface temperature of plate was measured by the thermocouple embedded in back surface of plate, the electric heating current and voltage were measured. The comparison and analysis are performed between the experiment results and calculated results. And all data obtained in this experiment were correlated as an equation. The results show that the Nusselt number deviations of the experiment and calculated with the classical relation increase gradually when the plate approaches the horizontal or the vertical. The deviation of data from the correlation was within plusmn27%.
